Deannexation
Simple solution to many problems: Deannex California TOTALLY.
Treat California as a hostile nation like North Korea. Disconnect all taxes and subsidies. Impose infinite tariffs and sanctions on all Calif shit, especially toxic "entertainment". Disconnect water flow from Lake Mead. Disconnect electricity from Bonneville Power Authority. Halt all oil pipelines and shipments.
California will then be forced to do all the ORDINARY NORMAL SANE things that it has been refusing to do, and it will no longer be able to PREVENT the rest of the country from doing ORDINARY NORMAL SANE THINGS.
California will face a beautiful Hobson's Choice on oil, water and electricity.
Either buy oil from Russia, or open up offshore oilfields and rebuild refineries.
Either start building more dams and desalination plants or dry up.
Either build nuclear power plants or go dark.
Try selling its poisonous "entertainment" to Russia and Korea and Indonesia.
